What about to add a new feature that [if activated by admin] can be used together with captcha and asks to the user that is going to subscribe (or post etc.), to respond to an [intelligent] question randomly chosen from a big customizable
Q) Who is the father's father
Q) Which are the first 3 letters of this web site domain?
Q) Who discovered America?
A) Cristoforo Colombo
Q) What color was the blue
horse of Napoleon?
Q) Insert this text into the field: 75)86/()121='
I have this idea because I'm noticing that captcha is no more effective and spammers can overcome it every day more often and for an admin the war against spam bots is going to be very problematic and very time consuming: in a single day I'm having about 1000 new spam posts and a lots of users that are registering an account in the forum but when I check it I discover that it is a spammer, because of similar data inserted in profile or the email or IP is into some spam database.
So I hope that this idea could help me and others to prevent or slow down this phenomena.
Thanks for reading captcha question
